Patent application number	Description	Published
20100103249	Stereoscopic image format with depth information - A multi-view distribution format is described for stereoscopic and autostereoscopic 3D displays. In general, it comprises multi-tile image compression with the inclusion of one or more depth maps. More specifically, it provides embodiments that utilize stereoscopic images with one or more depth maps typically in the form of a compressed grey scale image and, in some instances, incorporates depth information from a second view encoded differentially.	04-29-2010

20090128620	Demultiplexing for stereoplexed film and video applications - A method for demultiplexing frames of compressed image data is provided. The image data includes a series of left compressed images and a series of right compressed images, the right compressed images and left compressed images compressed using a compression function. The method includes receiving the frames of compressed image data via a medium configured to transmit images in single frame format, and performing an expansion function on frames of compressed image data, the expansion function configured to select pixels from the series of left compressed images and series of right compressed images to produce replacement pixels to form a substantially decompressed set of stereo image pairs. Additionally, a system for receiving stereo pairs, multiplexing the stereo pairs for transmission across a medium including single frame formatting, and demultiplexing received data into altered stereo pairs is provided.	05-21-2009

20080303895	Stereoplexing for video and film applications - A method for multiplexing a stream of stereoscopic image source data including a series of left images and a series of right images combinable to form a series of stereoscopic images is provided. The primary application is for video applications, but film applications are also addressed. The method includes removing pixels from the stereoscopic image source data to form left images and right images and providing a series of single frames divided into portions, each single frame containing one right image in a first portion and one left image in a second portion. Multiplexing processes such as staggering, alternating, filtering, variable scaling, and sharpening from original, uncompressed right and left images may be employed alone or in combination, and selected or predetermined regions or segments from uncompressed images may have more pixels removed or combined than other regions.	12-11-2008
20080303896	Stereoplexing for film and video applications - A method for multiplexing a stream of stereoscopic image source data into a series of left images and a series of right images combinable to form a series of stereoscopic images, both the stereoscopic image source data and series of left images and series of right images conceptually defined to be within frames. The method includes compressing stereoscopic image source data at varying levels across the frame, thereby forming left images and right images, and providing a series of single frames divided into portions, each single frame containing one right image in a first portion and one left image in a second portion. Alternately, single frames may contain two right images in a first two portions of each single frame and two left images in a second two portions of each single frame, wherein each set of right and left images may be processed differently. Multiplexing processes such as staggering, alternating, filtering, variable scaling, and sharpening from original, uncompressed right and left images may be employed.	12-11-2008
